1. A dishmachine comprising:
- an enclosure defining a wash chamber comprising at least one spray arm mounted therein and at least one spray nozzle on the spray arm, the enclosure further comprising a door and a vent;
a heat recovery system comprising;
a. a first flow path in fluid communication with the wash chamber through the vent, the first flow path comprising a first end disposed adjacent to the vent, a second end positioned opposite of the first end, and a drain, wherein the drain is in fluid communication with the wash chamber and adapted to drain condensate from the first flow path into the wash chamber, and wherein the first flow path further comprises an exhaust port positioned at the second end, and wherein the exhaust port is in fluid communication with the wash chamber and with an exterior of the dishmachine when the door is in a closed position;
b. a second flow path extending between and in fluid communication with an external water source and the wash chamber;
c. a refrigerant-boosted heat exchanger circuit comprising a closed loop circuit filled with refrigerant fluid, the circuit comprising a first coil extending into the first flow path and constructed and arranged to absorb heat from fluid in the first flow path; and
a second coil extending into the second flow path and constructed and arranged to release heat into fluid in the second flow path; and
an integrated water conditioning system.

10. A dishmachine comprising:
-
an enclosure defining a wash chamber comprising at least one spray arm mounted therein and at least one spray nozzle on the spray arm, the enclosure further comprising a door and a vent; a heat recovery system comprising; a. a first flow path connecting the wash chamber and an exterior of the dishmachine, wherein the first flow path comprises a first end comprising the vent and a second end comprising an exhaust port positioned opposite of the first end, and a drain, wherein the drain is in fluid communication with the wash chamber; and b. a second flow path extending between and in fluid communication with an external water source and the wash chamber, wherein the heat recovery system is arranged to transfer heat from fluid in the first flow path into fluid in the second flow path; and an integrated water conditioning system. - View Dependent Claims (11, 12, 13, 14, 15)
